Making
handmade paper is a mechanical process which basically consists
of two stages: the preparation of the pulp and the lifting
and finishing of paper.
The
preparation of the pulp depends on the type of raw materials
used:
Plant
residues are boiled, cleaned, washed, stamped in a mortar and
then processed into pulp in a beater (either a manual marina
beater or more sophisticated Carta or Bush beaters working on
a cycling mechanism or electricity).
The cotton rags are torn into pieces and left in a plastic
bag in the sun to start the initial decomposition. Afterwards,
the rags are washed and are processed into pulp in a Hollander
Beater, a stronger machine. Both types of beaters are designed
and produced locally by Handmade Papers of Africa.
Once
the pulp is prepared it is poured into a large basin where the
papermaker can lift the paper with a mould and deckle. The mould
is a line mesh used to separate the pulp from the water. The
deckle is a frame which determines the size of the paper. In
this lifting a distinction can be made between 'Western style':
paper with a smooth structure lifted by the mould and deckle
and 'African style': paper with a rougher structure lifted
with African mats.
After
lifting, the paper is couched on a feld (a piece of cloth) and
covered by a feld again, for the next paper to be couched. Once
a certain number of papers are couched the papers are pressed
in a hydraulic press to remove most of the water creating a
hydraulic bonding. After being pressed, the feld with the paper
is left to dry even further on a laundry line. When dried, the
paper can be taken off the feld and is pressed once more to
deliver a flat piece of paper.
The
whole process of paper making is chemical free, there are no
chemical additives, no glue and no chemical colourings. The
product is suitable for writing and printing (for copying, computer
printing and lithography). As different materials are used all
the time and every paper is unique, new paper is designed all
the time.
In
Zimbabwe the availability of forest-based raw materials is reducing.
The availability of energy and capital - as inputs for industry
- is limited. Therefore, the ecological handmade paper industry
offers a considerable potential to meet the increasing demand
for paper products in an environmentally friendly way. Exclusively
non-forest inputs are used in the production of ecological handmade
paper. The production can be organized in decentralized small
scale units, offering employment opportunities throughout the
country. Besides, handmade paper products can be regarded as
craftsmanship, capturing cultural aspects and providing an alternative
for tree or stone based crafts.
